Abstract :
The study on some physico-chemical characteristics of River Bhavani at its source and Mettupalayam and Sirumugai has been calculated for the period of one year (July 2007 to June 2008). The sampling points were selected on the basis of their importance. For surface water determination of water quality index becomes essential and pre-requisite. Analysis of some physico-chemical characteristics like water temperature, colour, electrical conductivity, transparency, total suspended solids, total dissolved solids, pC, dissolved oxygen,BOD, total alkalinity; total hardness has been done during the investigation period. Increase in temperature, turbidity, pH, electrical conductivity, total solids, suspended solids, dissolved solids, BOD values were higher in Sirumugai station, whereas the increase in total hardness, bicarbonate values were higher in Mettupalayam due to the intensity of expulsion of contamination. The dissolved oxygen values higher in Pillur dam station owing to unpolluted water. The Bhavani river has been facing severe anthropogenic activities, mostly due to municipal sewage and industrial waste and dense population etc.
